Description
The present invention relates to the smart card that is connected with mobile communications device, particularly communicating by letter between the device of mobile communications device outside and the smart card that is connected to this mobile communications device.
A kind of Subscriber Identity Module is called SIM card, is the smart card of the intrasystem mobile communications device of a kind of GSM of being used for (global digital mobile phone) (as in travelling carriage), comprising user totem information, and user's telephone number for example.This gsm system imports user's incoming call the travelling carriage at user's SIM place.This user can be by moving on to SIM card another device and change travelling carriage simply from a device.Except also having short message corresponding to SMS (storage management system) service, user's subscriber's number and other, described identification information can be stored in user's optional information in the SIM card.In addition, gsm system can be stored various control datas in SIM card.The structure of SIM card and gsm system was published by Palaiseau company in 1992, by " gsm system that is used for mobile communication " that Michel Mouly and Marie-Bernadette Pautet are shown, ISBN 2-9507190-0-7, in specific descriptions are arranged.SIM card has specific descriptions in GSM proposed standard ETSI GSM 11.11 and ISO/IEC 7816 standards.
Information about SIM card is organized with file mode, and in the file that writes down usually.SIM card is controlled by low-level command (perhaps be also referred to as APDU order), and the structure of this order has specific descriptions the 5.3rd section of ISO/IEC 7816-4 standard.For example, when sense information from SIM card, first order must tell this card to select specific file and data record.Then, by second order, the notified numerical value that returns described data record of this SIM card.
Therefore, stored information and the several orders that provide continuously by proper order of sense information needs from this card in this card.In the prior art, the proper order of order is to use the SIM card control element that receives order from other modules of this travelling carriage to guarantee, carries out and orders desired action by this, and possible result is turned back to the module of sending this order.In general, other module of travelling carriage shows its desired action only for high-level command of SIM card control element, and this SIM card control element is responsible for corresponding rudimentary APDU command sequence is sent to SIM card.
Fig. 1 illustrates an example according to prior art system.The system of this example comprises: the travelling carriage 1, SIM control element 4, SIM card interface 16 and I/O (I/O) interface 8 that comprise communications portion 6.This system also comprises a SIM card 2 and an external device (ED) that is connected to the SIM card interface, for example is connected to the portable computer of the input/output interface of travelling carriage.As a further example, this travelling carriage and external device (ED) can be individual equipment (for example, the portable multifunctional communication equipment) functional unit, this equipment comprises a mobile station apparatus and a computer, in this case, the input/output interface between this mobile station apparatus and the computer is positioned at the inside of this portable multifunctional communication equipment.Fig. 2 is illustrated in an example according to the message in the system of Fig. 1.
Fig. 2 illustrates an example according to the SIM card control information transmitting-receiving of prior art.This case description is the operation of SIM card control element 4 under certain conditions, and in this case, control element 4 receives new high-level command, and carries out by the desired SIM card command sequence of previous high-level command.For this example is described, comprise two communications portion module 6a, 6b in the example of Fig. 2, the information on their treatment S IM cards 2 also gives the SIM card control command high-level command.In practice, module 6a, 6b run on two software process handling difference in functionality in the processor of this travelling carriage.
SIM card control element 4 receives from other module 6a of travelling carriage, the steering command that is used for SIM card 2 of 6b, and handles SIM card according to this order.In the example of Fig. 2, the first module 6a of travelling carriage sends the order of fetching data to the SIM card control element, is used to get the IMSI sign indicating number of SIM card.The SIM card control element is responsible for giving SIM card rudimentary instruction.At first, SIM card control element 4 sends to SIM card 2 and selects the IMSI file command, and SIM card responds to return a confirmation signal.After receiving this confirmation signal, SIM card control element 4 sends one to SIM card 2 and reads the order of IMSI sign indicating number, and SIM card returns to control element 4 to required IMSI sign indicating number.The SIM card control element returns the first module 6a to the IMSI sign indicating number.
In the example of Fig. 2, in control element and SIM card exchange message, the second module 6b of communications portion sends storage SMS request to the SIM card control element.SIM card control element 4 does not begin to handle the order from the second module 6b immediately, but should order keep wait state, the task before this control element is finished.The IMSI sign indicating number is turned back to the first module 6a during the former task termination of SIM card control element, begun to handle Next Command then.At first, SIM card control element 4 sends to SIM card to the SELECT_FILE_SMS order, and after SIM card was returned a confirmation signal, this control element sent the UPDATE_RECORD_SMS order then.When SIM card was stored this SMS information, it returned to this control element to a confirmation, and this control element then turns back to the original directive that the second module 6b by communications portion is sent to a confirmation signal.
But when travelling carriage was connected to the external device (ED) of the information on the SIM card of manipulating this travelling carriage directly, the scheme of above-mentioned prior art went wrong.Particularly the SIM card control element of needs utilization such as this travelling carriage unknown new method, walk around the function of this travelling carriage, when handling the information on the SIM card fully freely, then can go wrong.For example when needing to create new GSM service, need this specific character.In this case, external device (ED) must send low-level command to travelling carriage, and at this moment the SIM card control element only is that this order is sent to SIM card.Because the SIM card control element is not known this command sequence that needs to carry out action required in this case, so it does not know whether the command sequence of being sent by external device (ED) is finished yet.Therefore, the SIM card control element may begin to carry out the order of being sent by other module of travelling carriage in the centre from the command sequence of external device (ED), so just makes the mistake.In addition, be connected in a plurality of SIM card under the situation of a travelling carriage according to the scheme of prior art and also can go wrong.
Fig. 3 illustrates the situation that may go wrong according to prior art.In this example, a travelling carriage is connected to the external device (ED) 12 resemble the portable personal computer.In this example, the SIM card 2 of travelling carriage is used by this mobile communications part 6 and described outer computer 12.At first, this computer sends the SELECT_FILE_ADN order to select required file and record to travelling carriage.SIM card control element 4 is passed to SIM card 2 to this order, and SIM card is returned a confirmation signal.At this moment, according to the requirement of external device (ED), the AND data record is selected in SIM card.The communications portion 6 of travelling carriage is sent the UPDATE_BCCH_INFO order to the SIM card control element then, and the SIM card control element sends the select command that is used for file and BCCH data record to SIM card.Confirm this BCCH when SIM card and write down when selected that SIM card control element 4 sends the UPDATE_BINARY_BCCH order, and when this record was updated, SIM card was returned a confirmation signal to control element once more.Then, control element 4 returns a confirmation signal to the communications portion 6 of travelling carriage, shows that this sequence finishes.When external device (ED) 12 sent the Next Command UPDATE_RECORD_ADN of its command sequence, this order was passed to SIM card by the SIM card control element then.In this stage, the data record of selecting in SIM card is BCCH, and does not have that outer member is inferred and by order UPDATE_RECORD_ADN desired ADN.Because ADN and BCCH data record are dissimilar, therefore, SIM card detects mistake and returns error notification UPDATE_RECORD_ADN_FALSE, and this notice sends it back external device (ED) by the SIM card control element then.
The data record types of selecting in the former command sequence is that bigger mistake can go wrong under the situation identical with the desired record type of order that is sent by external device (ED).In this case, because data record types is correct, but returning an affirmation shows this order by successful execution, so SIM card will not detect mistake.In this case, external device (ED) will not detect mistake, and data are to be stored in the wrong file.
